Real-world examples

  • 자, 시작해요!

    ja, si-jak-hae-yo!, ja, si jak hae yo!

    '자' is appropriate as an urge for immediate action in a suggestion sentence.

  • 자마자 시작해요!

    ja-ma-ja si-jak-hae-yo!, ja ma ja si jak hae yo!

    '자마자' indicates immediately after an action ends, so this structure is incorrect; '끝나자마자 시작해요' is correct.
